The effect of the anion, namely dicyanamide, hexafluorophosphate, trifluoroacetate, or trifluoromethanesulfonate, on the cond. (κ) of 1-N-butyl-3-N-methylimidazolium-based room-temp. ionic liqs. (RTILs) was studied over the temp. range (248 to 468) K. The uncertainty in κ was estd. to be less than 0.5 %. The cond. values obtained are well-described by the Vogel-Fulcher-Tammann equation. Addnl., densities (ρ) and the corresponding molar conductivities (Λ) are reported for the temp. range (278 to 338) K. The data for Λ and the assocd. viscosities (η) were found to fit fractional forms of the Walden relationship.
